Chaldea, often referred to in ancient texts, was a region situated in the southernmost portion of Mesopotamia, encompassing the marshlands near the confluence of the Euphrates and Tigris rivers. It rose to prominence during the first millennium B.C. and is most notably recognized for its association with the Neo-Babylonian Empire. During a time when the Kingdom of Babylonia was experiencing periods of weakness, Chaldea became influential, particularly when Chaldean kings assumed the throne of Babylon. The Book of Mormon references Chaldea in the context of prophecies taken from the writings of Isaiah, which are quoted by Nephi. In these passages, the Lord speaks of his intended actions against Babylon and how his “arm shall come upon the Chaldeans” (1 Nephi 20:14), signifying forthcoming divine judgment similar to that which befell Sodom and Gomorrah. Additionally, there is an admonishment to “flee ye from the Chaldeans” (1 Nephi 20:20), indicating a call for the people to distance themselves from the impending destruction of that nation. Furthermore, the Book of Mormon describes Chaldea as part of Babylonia (2 Nephi 23:19), essentially serving as a name for the broader territory in certain historical periods. The beauty and excellence of Chaldea’s most famous city, Babylon, are recalled, with a foreboding comparison to the fate of Sodom and Gomorrah, underscoring the severity of the prophesied devastation.
